I'll move faster than it can keep up with...
...سأتحرّك أسرع ممّا تستطيع مواكبته
Und zwar das Herz der Rüstung
so schnell zu durchstoßen,
Me moveré más rápido que ella…
Être plus rapide que l’armure
Mi muoverò più velocemente 
di quanto non possa fare lei...
Ser mais rápido do que

Буду двигаться быстрее доспехов...
